Metallic clinking noise

Hi!

This happens just sometimes, and when it does, only at low RPM. (idle - 2000RPM) I was lucky that the sound came just as I came back from my ride so that I could record it.
The bike is a little hard to start, but give just a little gas and she starts right up. The same when she is hot. Otherwise she seems to work flawlessly. I am riding hard and almost touching the redline before shifting. No problems.
Seems like something is loose? It stops and starts and stops and starts. Then it sounds fine. I go riding for a while and then there it is again.

Thank you

Seems I can't post links yet... w w w .youtube.com/watch?v=ghaUtRGMdHI

Kind of sounds like its a separate sound not part of regular engine noises, does the sound follow engine rpm, if not maybe pull off the plastic and check for anything loose or vibrating against something.

Totally forgot about this post. Thank you 02RC. My suspicion as well. I will remove all the plastic. Maybe beat it up with a rubber mallet :P

Only happens when she's warm... The mysteries!

Does it only appear when the fans are running?
If so, the fan motor bearings may be squeaking and starting to go.

Do this when the engine is cold. Reach in from the front and give each fan a quick spin by hand.
Make sure each fan spins freely and without binding or rubbing on the radiator.
If the fan stops immediately when spun and is not rubbing on the radiator, the bearings may be on the way out. They may also squeak when rotated.

I had one fan motor (left one) years ago that stopped immediately when spun and squeaked when rotated, indicating the fan motor bearings were toast.
I replaced both fan motors, and problem solved.

Thank you! I will try that!

Checked both fans. No problems.

Going to change plugs and filters tomorrow, so I'll rip all the plastics off while I'm at it to try and locate the sound.
